SAW LIFT.

Application filed February To ZZ 'fw/wm t may concer/n.'

Be .it known that I, .loi-IN II. Kmrrnn, a citizen of the United States,residing at Charlotte, in the county ofl Mecklenburg and State of NorthCarolina, have inventedA a new and useful Saw Lift, of which thefollowing is a specification.

r1`his invention aims to provide novel means whereby an operator maylift a back saw whilst the same is being used in a miter box.

It is within the province of the disclosure to improve generally and toenhance the utility of devices of that type to which the inventionappertains.

`With the above and other objects in view which will appear' as thedescription pro-Y ceeds, the invention resides in the combina-- tion andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understoodl that changes in the preciseembodiment of the invention herein -disclosed may be made within thescope of what is claimed without departing` from the spirit of theinvention.

In the accompanying drawings Figure 1 shows in perspective, a deviceconstructed in accordance with the invention, the saw being lowered;Figure 2 is a similar view wherein the saw is shown raised; Figure 3 isa` transverse sectional view showing the guide; Figure 4 is a fragmentalelevation disclosing the keeper wherewith the operating member coacts;and Figure 5 is a section on the line 5-5 of Figure 4.

The numeral 1 marks a miter box including' standards 2 which. areslotted at 3 to receive, for reciprocation, the blade 4 of a saw 5including a back 6 and a handle 7. Posts 8 are vertically slidable inthe standards 2 and are supplied at their upper ends with enlarged heads9 having openings 10 wherein the back 6 of the saw is received, theconstruction heilig such that when the saw 5 is raised, or lowered, theposts 8 will participate in thc movement and slide vertically in thestandards 2. The construction above alluded to is common, and no noveltyis claimed for it, saving in so vfar as it may enter into patentablecombinations with parts hereinafter described.

In carrying out the invention, there is provided a gui-de 11 having apassage 12 and a slot 14, theV back 6 of the saw being mounted .QITrecprocation in the passage 12,

and the blade 4 of the saw being mounted for reciprocation in the slot14. n A fulcrum bracket 15 is secured at 16y to one of the standards 2,and projects therefrom. The numeral 17 designates a radius arm which 1spivoted at one end, as indicated at 18, to the fulcrum bracket 15. Thenumeral 19 denotes an operating member located at an acute angle to theradius arm 17, the operating member being supplied in its upper edgewith a rack 20. The operating member I19 slides in a guide slot formedin the lower edge of a laterally extended keeper 21 se cured at 22 onthe head 9 of one of the posts 8. A spring 26 is secured at 27l to thekeeper 21 and bears against the lower edge of the operating member 19.At one end, the operating member 19 is supplied with a handle or fingersocket 24. Through the instrumentality of a pivot element 28, one end ofthe radius arm 17 and the corresponding end of the operating member 19are connected for swinging movement to the guide 11.

In practical operation, when the operator wishes to raise the saw 5, heslips one finger of the hand which is engaged with the handle 7, throughthe socket 24 and draws the saw backwardly into the position shown inFigure 2, the radius arm 17 cooperating with the guide 11, to raise thesaw, the rack 2O on the operating member 19 being engaged automaticallywith the keeper 21, by the action of the spring 26, to hold thel sawelevated, the operating member 19 sliding in the guide groove 25 of thekeeper 21.

I-Iaving thus described the invention, what. is claimed is A miter boxincluding standards, posts slidable in the standards and provided withmeans for receiving a saw slidably, a guide Y disposed between the postsand provided with means for supporting a saw for sliding movement, aradius arm, means for mounting the radius arm pivotally on one post,means for connecting the radius arm pivotally to the guide, an ope atingmember pivoted at one end to the guide, and means can ried by" onestandard for supporting the operating member for movement in a directionsubstantially parallel to the direction in which a saw moves in thestandards and in the guide.
